If you have a set of dumbells (optional ) and a mat that's all you need for this 45 minute Cardio & Core workout.  Short on time?  Try just 12 minutes of this 3 part combined series found under 12 minute Quickies section.

This full bodyweight cardio and core workout  with Coach Kat is 36 minutes long with 3 minutes of cardio followed by 3 minutes of core for 2 rounds.  We perform 3 different segments/groupings of exercises for a great and challenging variety!  Sadly, the last 4 minutes got cut off :( but I recommended stretching with a 12 minute stretch from the workout quickies section or stretching on your own after the workout is complete.
